Answer:
875 Watts
Step-by-step explanation:
Given that :
P α s²
P = ks²
Where k is the proportionality constant
When ; p = 1260 ; s = 30
1260 = k * 30²
1260 = 900k
k = 1260 / 900
k = 1.4
Value of p ; when s = 25
P = 1.4 * s²
P = 1.4 * 25²
P = 1.4 * 625
P = 875 watt
To make this easier, we can convert the fractions into decimals. 3/4 is 0.75. 1 and 1/2 would be 1.50 and 2 and 1/4 would be 2.25. Now, let us to the subtraction in order for us to know the difference of each. So 1.50 minus 0.75 would be 0.75. And 2.25 minus 1.50 is also 0.75. 0.75 is 3/4 and this means that she increased 3/4 hour each day.
Answer:
The answer to your question is 12 ft
Step-by-step explanation:
Data
Height of the flag pole = 24
shadow of the flag pole = x
height of the man = 5 ft
shadow of the man = 2.5 ft
Process
1.- Use the Thales' theorem to solve this problem
shadow of the flag pole/height of the flag pole = shadow of the man/height
of the man
- Substitution
x/24 = 2.5/5
- Solve for x
x = 2.5(24)/5
- Simplification
x = 60/5
-Result
x = 12 ft
